Hot Knife spare part

I have a ZTA Thermo Schneider 20 used for cutting plastics. (pic attached)
The operating lever operates a lever Microswitch ...
CHERRY model G62 250V 10A
(pic attached)


Does anybody know where I could get a replacement.
Or if there is a CHERRY main dealer in UK

It's a very common microswitch made by many different manufacturers.
Just search ebay etc. until you find one the right size/lever/pinout.

I searched using "pcb mount microswitch" and several came up, it all depends upon the dimensions of yours.
The 10A aspect may be way more than is required, the wattage of the heater may be far less allowing a lesser switch.

Are you 100% sure that the switch is faulty? Have you tested it with a meter?

Yep it’s u/s, normally closed is working, but normally open no action.
… assuming this has a modified lever, a straight lever would do and I’ll modify.
I have been looking on eBay, but not found one with contacts in right orientation yet.

Certainly look possible …do you know if mounting holes are standard diameter & spacing.

If not I can try asking seller.

Thank you

Update … I used this switch and bent the lever to match.
Repaired & working again.
I’m guessing the very high current on secondary, creates a huge back emf when you release actuating button.
This maybe why switch failed.


Thank you.
