Vandal resistant switch (sometimes referred to as vandal proof switch or tamper-proof switch) are electrical switch designed to be installed in a location (or device) and application where they may be subiect to vandalism or tampering, as in the case of pedestrian crossing switch, or fraudulent or unauthorized use, as in the case of vending machine switch.

Vandal resistant switch that are located on devices that are accessible to the public or which are located outside also have to be able to withstand dust, rain, snow, and frequent operation.

Vandal-resistant switch are frequently constructed of stainless steel or other durable metalsand mounted into panels or housing boxes made out of strong materials, such as polycarbonate plastic, aluminium, or stainless steel. In some cases, the housing may be 1/4'' thick, to protect both the switch and the housing from attempts by vandals to damage the switch or housing using blunt force. The housing for vandal proof switch is often secured using security screws (which cannot be unscrewed with regular screw driers). The height of buttons in the panel is often minimized by using flush-mounting, to make it more difficult to pry them out, a design technique used in ATM banking machines that are located outside. Some vandal-resistant switch are protected against tampering using other approaches, such as hiding the switch behind a locked or screqed-down door-covered panel, or by requiring a key or passcode before the switch will operate the device.

关于压电开关 About Piezo Switches

Electrical and general specifications:

Conventional electromechanical switches have moving parts that inevitably wear out.The reliability of the electromechanical switches can be reduced by contaminants such as

moisture and dust that will foul contact points.The solution is a Piezo Switch with no moving parts.The switch is not polarity sensitive: (+) and (-) wires can inversed without any risk.

• Max. Current/voltage rating: 200mA 5~24VAC/DC/ 1A 24AC/DC• Switch resistance ON: 10 max.• Switch resistance OFF: 5M min.• Operating force: 6 to 15N• Life expectancy: 50 million cycles• LED consumption: Illuminated dot: 10mA - Illuminated ring: 20mA

朗齐尔压电开关有着和标准的普通开关一样的功能：开关被按压的时间越长，其输出持续的时间越久——最长可达 20秒。

该款开关只有 2根接线，可以直接替换现在普遍使用的各类按钮开关，并有着更长的使用寿命，以及全密封、可水洗的特性，同时具有更为现代化的外观设计，多种颜色可供选择。

该款开关适合各类高要求的应用场合，如医疗、测试、矿产开采、食物加工、自动售货机及遥控器等各类设备。

产品特色

• 无需外接电源，无电源 /接地线，无能源消耗，并且没有任何电子界面，因

此使用极其方便。

• 延长的脉冲输出减少了错误触发的可能，并方便了需要逐级增加设计中的多

次按动的不便。

• Max. voltage rating: 24VDC• Max. current rating: 200mA• Supply voltage: 5 to 24VDC• Life expectancy: 50 million cycles• Operating force: 0N• Output type: NPN

Electrical and general specifications

The new CP Series Capacitive switch technology senses the touch of a finger and creates an electrical charge to activate the switch. An auto-calibration function ensures the sensor adapts to changing external environments. LANGIR's capacitive switches are specially designed for durability and a low activation force. As sensitive as a touch screen, the capacitive switches are perfect for industrial applications where repetitive activation can cause operator fatigue.

• Activated by the easy touch of a finger, the capacitive switches extremely to use• Adjustable sensitivity sensor adapts to external environmentsEasy-to-locate or on/off indication is possible through independent or output image LED functionality• Easy to clean because the switch is impervious to dust and dirt, and resistant to harsh chemicals and contaminants• 50 million cycles and no moving mechanical parts make LANGIR's CP Switches robust and durable• Available in momentary or latching and with or without illumination

Extreme ease of use/ Adaptable/ Easy-locate or on/off indication/ Easy to clean/ Robust and durable

Benefits:

• Sealing: IP68/ IP69K• Triggered by flowing water• Impact resistance: IK10• Operating temperature: -20℃ to +65℃ • ESD: complies with EN61000-4-2 (extended) ±8KV (20 contacts) and ±15KV (20 air discharges)

The JB is a DC circuit breaker dedicated to multi string photovoltaic installations.This circuit breaker is designed to protect the cables located between each string of photovoltaic modules and the photovoltaic inverter against overloads and short circuits (see application diagram).Combined with a switch, the JB will be installed in a string PV protection enclosure at the end of each string of photovoltaic modules.It can be locked (by a padlocking device) in OFF position as a safety measure for removal of the PV inverter.Since a fault current can flow in the reverse direction to the operating current, theJB can detect and protect against any bidirectional current.To ensure the safety of the installation, it is necessary, depending on the various types of application, to combine the JB with:• a residual current device at the AC end,• a fault passage detector (insulation monitoring device) at the DC end• an earth protection circuit breaker at the DC endIn all cases, fast action on site will be required to clear the fault (protection not ensured in the event of a double fault).JB is not polarity sensitive: (+) and (-) wires can inversed without any risk.The JB is: delivered with three inter-pole barrier to provide increased isolation distance between two adjacent connectors.
