Toggle Switches are Sealed on the Panel

A new range of military style toggle switches feature moulded-in terminal inserts and a silicone membrane feature for IP67 front panel sealing.

New from Apem Components, 3500 series military style toggle switches feature moulded-in terminal inserts and a silicone membrane feature for IP67 front panel sealing.

Typical applications include hydraulic crane controls, racing cars, military communications equipment, military vehicle panels, boating equipment and generator control panels. These robust, high reliability models carry contact ratings ranging from 15-20A with a minimum life of 6000 cycles at alternating current.

Single and double pole models are offered in an extensive range of electrical configurations, including the popular on-off, on-on, momentary-off-momentary, on-off-momentary and on-off-on.

Other electrical specifications include maximum initial contact resistance of 10mohm, minimum insulation resistance of 100Mohm, and dielectric strength of 3000V RMS between terminals and frame.

The standard actuator is a chrome or nickel plated bat, 6mm in diameter and 17.5mm long, with several additional options, including a flatted style and a fluorescent tip for visibility under adverse glare conditions.

Additional actuator finishes are available.

Locking actuator styles are also available for those critical safety applications where deliberate action is required to actuate the switch, or where positive resistance against excessive shock or vibration is essential.

The single-pole body size is 15 x 32 x 31.4mm, while the double pole is 23 x 32 x 31.4mm.

Solder lug/quick-connect or screw terminals are available.

Superior quality engineering materials include silver alloy contacts and UL94V0 rated case material.
