Snap Action, Limit Switches are common components in automation, control and instrumentation systems. The functions include protecting machinery, activating machine alarms and safety interlocks, as well as providing the starting and stopping input of high speed and ultra-high speed motors.The D3V-16-3A4 is a high performance, family of miniaturised snap action switches with a 16A rating at 250VAC and a 4A rating at 28VDC making them suitable for a wide range of applications.The D3V-16-3A4 switches are available in three operating modes: momentary, alternate/maintained, and slow make/slow break, thereby giving flexibility to the user to accommodate the most complex machinery. The multiple mounting and actuator options allow for panel, pcb and board applications.The D3V-16-3A4 switches are designed for the most challenging industrial environments, with the ability to withstand temperatures ranging from -10 to 65 degrees Celsius. The precision design prevents false triggers, caused by vibrations and acceleration changes and improves the overall reliability and life of the switch.It features a snap action, precision button contact to ensure high repeat accuracy and a phenomenally long life beyond 5 million cycles. The tight contact gap distance prevents contact bounce and improves the electrical integrity of the switch.The electrical connections are via 6.3mm fixed spade connectors. The connectors are looped for extra protection and can accept wire sizes up to 4mm2. The D3V-16-3A4 is also available with a yellow LED indicator, which provides visual indication of the on/off status.The D3V-16-3A4 switch is an ideal choice for general purpose switching applications in industrial, commercial and consumer markets. Common applications include home automation, lighting control and door interlocks, safety interlocks in machinery, and other process and automation applications.This ultra-miniature switch offers exceptional operational performance in a variety of demanding applications. Its low power consumption, ease of installation and flexibility make it suitable for almost any application.Its working principle relies on a plunger embedded in a spring-loaded housing that pops into place when the switch is operated. Depending on the switch specification, when the plunger is extended, the switch is turned on, and when collapsed, the switch is turned off. Once the switch has been activated, the spring action is designed to snap the plunger back into its original position.This device eliminates the possibility of cross-circuit voltage shorts, providing superior electrical protection for the contact and extended switch life. The snap action switch will provide reliability for many years of operation and precise, consistent switching ensuring that critical applications can continue to operate reliably.
