Waterproof membrane switch

►Basic info
Waterproof membrane switch in a humid environment can prevent water or moisture from permeating into the membrane switch edge cracks panel and equipment shell.Waterproof membrane switch can be used in outdoor or high humidity environment.

►Structure presentation

►Waterproof Solution

(1)structure design - with waterproof sealing ring;
(2)material selection - use waterproof adhesive which will not fail in the immersion water leakage.

►Note on mounting and operation

①The stick process is finished in one time.Tearing off the pasted switch will affect the adhesion of the back and damage button and electronic components.
②Be gently when mounting.Do not pull the tail with force.
③It is required to stick on the smooth surface of ABS, PC, stainless steel, aluminum plate, etc., and there is no dust, water or other solvent on object surface.
④Pasting and mounting operation temperature needed:15~30℃，RH40%~70
⑤The min bend degree is R=2mm
⑥Input voltage and current shall meet the performance requirements of the switch.
⑦Do not use hard objects like screwdriver,metal stick in case of any malfunction on pressing buttons.
⑧Don’t knock button by heavy objects.
⑨Use it in required environment
