*2. The pin plungers of reverse-type models are continuously pressed by the actuator levers with compression coil
       springs and the pin plungers are freed by operating the levers. Reverse-type models are highly vibration- and shock-
       resistive because the pin plungers are normally pressed.

Accessories (Order Separately)

Drip-proof Terminal Cover (Order Separately)

The Drip-proof Terminal Protective Cover is provided for maintenance for Z-[]A55-B5V Switches.

Name Model
Drip-proof Terminal Protective Cover AP-DV

Terminal Covers (Sold Separately)

The Terminal Covers can be attached to Z, A, X, and DZ Switches.
The Terminal Cover is secured with mounting screws and protects the casing and terminal wires from dust, vibration, or fingers, thus preventing terminal short-circuiting, ground faults, wire disconnection or improper connection, and electric shock accidents.
Terminal Covers made of phenol resin have five or six thin wall sections. These sections can be torn open for providing holes for lead cables at desired points.
A terminal cover can’t be used in the case of using an actuator sold separately.

Note: Use a Terminal Cover for screw terminals fir DZ-series Switches with soldering terminals.

Separator (Sold Separately)

Use a Separator when it is difficult to provide a sufficient insulation distance or when using the Switch near metal parts or copper wires.
