PM Miniature Oiltight Controls

The pushbuttons and indicating lights available in the PM Miniature Oiltight Controls line provide a great deal of flexibility in a small package with up to 4 lights in an approximately 1″ square face plate. (the mounting size is a 22.5 mm round hole). Contact blocks provide up to 4 SPDT silver or gold, momentary or alternating contacts. Digital legend films and color inserts fit inside the clear operator. Great panel space utilization!

PM modular mechanical switching elements consist of Senasys proven snap action basic switches, keyed mounting bracket, & operating mechanism. Their modularity permits circuit flexibility: 1,2, 3, & 4 Form C (SPDT) circuits, & Form Z (2 CKT DB) contact arrangements’ momentary & alternate-action. Operation is positive as circuits cannot be teased. The switching element mechanism also imparts a snap feel to pushbutton operation.

PM terminals are well exposed for easy, direct back-of-panel wiring even after the devices are installed in the panel. Most lamp & switching element terminals are on a common level. Terminal identification is molded into the operator housings & switch cases.

Molded & tube type insulators are available to further isolate and protect the connections of the dual push-on terminal.

PM mechanical devices are offered with three push-on terminal styles: dual tab & single pin.
