FH TYPE SMALL-SIZE CAM-OPERATED SWITCH
FEATURES
Structure for efficient wiring work
With the back terminal mechanism, the wiring terminal unit can be separated from the operation unit body.
(This structure makes more efficient wiring work.)
4-type product lineup
The following four types of switches are available in the product lineup:
1) Manual return type (2-notch, 3-notch)
2) Handle removal type (2-notch, 3-notch)
3) Automatic return, push type
4) Automatic return, pull type
Compact and space-saving
The minimum mounting pitch is 42 mm (horizontal) and 65 mm (vertical), enabling on-board wiring. It can be mounted in the increasingly limited space of control panels.
Maximum wire size: 2mm2
Wire of up to 2 mm2 can be connected.
(Terminal screw size: M3.5)
Terminal cover comes as a standard accessory
The terminal cover is provided as a standard accessory which prevents accidental contact with live parts.
(The handle cover is optionally available.)
Highly-reliable contact mechanism
The contact operates with a rolling action mechanism: First, the movable contact touches the fixed contact at one point and gradually increases the contact area while sliding on the contact surface. This mechanism can minimize the area exposed to arc during first contact and breaking.
Easy-to-see circuit condition
Round and square type metal nameplates and flange nameplates are available. The circuit condition can be directly indicated on the nameplate.
