APEM Offers High Performance, Environmentally Sealed Toggle Switches

Featuring molded-in terminal inserts and silicone membrane for IP67 front panel sealing, military style Series 3500 withstands 0.1 bar pressure under total immersion. Switches carry contact ratings from 15–20 A with minimum life of 6,000 cycles at alternate current. Single and double pole models are offered with initial contact resistance of 10 mΩ max, insulation resistance of 100 MΩ min, and dielectric strength of 3,000 Vrms between terminals and frame.

Can withstand 0.1 bar pressure under total immersion

Haverhill, MA - APEM Components, Inc., a leading manufacturer of high quality miniature and industrial switches, offers the 3500 series military style toggle switches, featuring molded-in terminal inserts and a silicone membrane feature for IP67 front panel sealing. Typical applications include hydraulic crane controls, race cars, military communications equipment, military vehicle panels, boating equipment and generator control panels.

These robust, high reliability models carry contact ratings ranging from 15-20 amps with a minimum life of 6,000 cycles at alternate current.

Single and double pole models are offered in an extensive range of electrical configurations, including the popular ON-OFF, ON-ON, MOM OFF MOM, ON OFF MOM and ON OFF  ON. Other electricals include initial contact resistance of 10 milliohms max., insulation resistance of 100 megohms min., and dielectric strength of 3000 V rms between terminals and frame.

The standard actuator is a chrome or nickel plated bat .236” dia. X .688” 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 .591”w x 1.260”h x 1.236”d, while the double pole is .905”w with the same height and depth. Solder lug/quick-connect or screw terminals are available. Superior quality engineering materials include silver alloy contacts and UL94-VO rated case material.
