KL series Locking rocker switches Distinctive features Unlocking actuator Protection frames Unlocking actuator Each KL rocker switch includes an unlocking actuator. This actuator must be pressed to activate the protected function of the rocker. Moreover, two frames protect the unlocking actuator from untimely activation. This intuitive and secured ergonomics is patented by APEM. 2 position versions (electrical functions 1, 5 and 6) Press unlocking actuator to reach the protected position Press opposite part of actuator to leave the protected position 3 position versions (electrical functions 7, 8, 9 4, 4-1R) Press unlocking actuator to reach the protected position 12 Press opposite part of actuator to leave the protected position www.apem.com APEM KL series Locking rocker switches Specifications One protected position Patented intuitive ergonomics Wide choice of colours Laser etched symbols Illuminated or non-illuminated ELECTRICAL SPECIFICATIONS MATERIALS * Currrent/voltage rating with resistive load : - Silver contacts (A) : 5A 24VDC, 100.000 cycles 10A 24VDC, 10.000 cycles (terminals 6.35 x 0.8 only) - Gold plated contacts (D) : 20mA 12V, 150.000 cycles * Initial contact resistance : 10 m max. * Insulation resistance : 1.000 M min. at 500VDC * Dielectric strength : 2.000 Vrms 50 Hz min. between terminals * Mechanical life : 150.000 cycles min. * Case : PA 6-6 * Actuator and unlocking actuator : ABS * Bezel : PA 6-6 * Terminals : brass, silver plated * Contacts : silver (A) or silver, gold plated (D) * Contact roller : brass, nickel plated ENVIRONMENTAL SPECIFICATIONS SEALING * Degree of protection of sealed versions : frontal sealing to IP68 according to IEC 60529 (submersion under 1 meter of water for more than 30 minutes) * Salt spray resistance : 96 hours according to IEC 512-6, test 11f * Operating temperature : -40C to +85C Sealing is optional.
