LOW ENERGY SWITCHING

In today???s demanding age of low energy controls, electromechanical switches are frequently used to interface directly with safety relays, PLCs and other low energy devices. To accommodate this requirement GSS offers gold plated contact versions of the standard basic switch. This improves reliability of switching at low currents and voltages, by protecting the contact surfaces from contamination during opera- tion or storage prior to use.

Standard silver contacts have a disadvantage in that the contact surface may tar- nish under certain environmental conditions e.g. in the presence of moisture.

Low energy basic switches are rated as follows:
