Design Feature
LA423 series pushbutton consists of 3 parts-contact block, bracket and button head, Connection among which adopts the international current
self-locking connection of no-fastener firmware. It is safe, reliable, convenient to mount and dismoun (only one can do it ) and longevous.
Contact block's touch safety is reliable.
Parts are made of imported materials, wearable and durable.
Simple inspection (only one screwdriver needed to change all components one the back side of the panel.)
Degree of protection of open head: IP65, some products can reach IP67 with protective membrane(cid:13)(cid:10)
One LA42 series pushbutton can contain 3 contact blocks, 6 couples of contact numbers at most. Combination modes of contact are showed as follows:
1NO:10; 1NC:01; 1NO+1NC:11; 2NOs:20; 2NCs:02; 2NOs+2NCs:22; 3NOs:30; 3NCs:03; 3NOs+NCs:33
