Cam Switches Ammeter/Voltmeter

General Details

Cam Switches Ammeter/Voltmeter

Cam Switches Ammeter/Voltmeter type are a high quality rotary style type of switch , CSA rated, up to 600V, 15 amps. These units feature a compact rugged design, with a 48 mm front plate.

Cam Switches Ammeter/Voltmeter type are commonly used with analog panel meters & utilize high quality silver alloy contact coating for maximum performance.

Advantages of Cam Switches are ease of use, lower cost, compact size, no need for maintenance, usability in ac and dc applications, mounting diversity (eg. panel door, or enclosure), contact diversity, and temperature independent operation.
