Snap Action, Limit Switches

The ZV50E20S01-A is a miniature snap action limit switch. It features an adjustable and removable guard head, a metal lever arm, two screw terminals, and an integral vibration damper. The device is designed for use in a variety of applications, including industrial, household, and medical equipment.

Applications

The ZV50E20S01-A is well-suited for use in home appliances, small machinery, and medical equipment. It can be used to monitor door or drawer openings, low or high temperatures, and humidity levels. It is also useful for sensing the presence of a pin, lever, knob, or other control arm. In commercial security settings, the switch can be employed to detect the presence of an object in a restricted area.

Working Principle

The ZV50E20S01-A functions by sensing the presence of a mechanical force. To begin, power is applied to the switch, activating its internal electromagnetic coil. This causes the switch to "lock" in place and the contact points to remain closed. When a force is applied to the guard head, such as from the depression of a button or lever, the motion causes the contact points to move apart.

The reaction to this movement is a "snap" sound, signaling that the switch has been depressed and the contact points have opened. Upon releasing the pressure, the contact points automatically close and the switch resets back to its "locked" position. This process repeats itself each time the switch is triggered, providing a reliable and efficient method of actuation and control.

Conclusion

The ZV50E20S01-A is a miniature snap action limit switch designed for use in a wide variety of applications. Its adjustable guard head, metal lever arm, and two screw terminals enable easy installation in a range of locations. The switch\'s working principle is based on the reactivity of a spring-loaded arm to external mechanical force. This enables it to detect an opening, closing, or presence of a control arm. With its compact design and adjustable settings, the ZV50E20S01-A is a versatile, reliable, and cost-effective solution for many types of industrial, household, and medical equipment.
