Non-locking switch for filter monitoring
First Claim
1. A filter-monitoring switch comprising:
- first and second contacts for connection to an electric circuit;
a conductive member for electrically coupling the first contact to the second contact;
a diaphragm coupled to move the conductive member; and
a push plate coupled to the diaphragm and having a central pin coupled to the conductive member.

Abstract
Commercially available filter-monitoring switches suffer from problems related to over sensitivity and reliability. Accordingly, the present inventors have devised, among other things, various embodiments of filter-monitoring switches and related components, subassemblies, methods, and systems. One exemplary filter-monitoring switch includes a diaphragm operably couple to move a conductive element back and forth between a pair of fixed terminals in response to pressure differences across the diaphragm. The conductive element is mounted to an insulative pin of substantially uniform width, and the terminals include leaf contacts that constantly engage the pin or the contacts throughout normal operation of the switch, thereby reducing flexure of the contacts and effectively providing a self-cleaning and self-healing electrical switch.
