Tamper/Plunger Switch - TS-20 Series  - 10 Pack

The adjustable plunger actuated switch was developed to provide a tamper switch with a smaller diameter for applications where a normal plunger or roller ball type switch is too large. The 3/8" diameter is ideal for a variety of door and window applications. The oval flange allows the switch to be solidly anchored where needed. The design also resists locking problems caused by expansion or contraction. Made of nylon for flexibility, the stainless steel spring and sealed contact ensure a long service live.

Note: Open Loop or "normal open" means the switch is open when magnet is in close proximity.
