Hoist Push-Button Switches
COB 60 series
For Indirect Operation of Electrical Machinery
Outline
Power
Switches
The COB 60 series is a push button switch for indirect
operation via electro-magnetic switches. It is small, light,
and economical.
Basic type list
Type name
Button packing is included inside the case, built-in structure.
It is possible to manufacture types other that the standard
of cable bushing and character boards, etc. The attached
cable bushing of COB64 and COB66 is supposed to be
used for vinyl cabtire cable.

Appearance
The standard case is made with high impact ABS, and is
light and safe with no risk of electrification.
The mechanical interlock is included for safety, so Up/Down
and East/West cannot be pressed at the same time.
COB61, COB 62, COB 63 have type attached with power
on/off unit which is convenient for opening/closing of the
main circuit and switch on/off of the light (COB61UNB,
COB62UNB, COB63UNB). The installing position of power
on/off unit is at the uppermost.
Operating Push
Button Switches
Using twin contact, we also have available a type built in
with a switch unit that can correspond to a minute load
(COB61W, COB 62W, COB 63W, COB 64W, COB 65W).
The on/off switch is not twin contact. The contact reliability
of twin contact is confirmed and proven usable without
problems through the test using the circuit condition of DC
12V 10mA.

・Installation method for COB A1, A2, B1, B2 cable bushing
The cable is fed through the bushing holder, bushing, and packing in that
order, and the tightening screw used to secure the bushing holder firmly to
the case.Two packings are prepared as a set. Check the cable range
displayed on the packing, and separate off the applicable one.
In terms of C7 to C19 cable bushing, the bush and packing are integrated.

Reference :
When inserting into the bushing, it is
recommended to lubricate the cable
and cable slot with wet soap to ease
insertion. Do not use lubricating oil,
as this may damage the bushing.
