Re: Hydraulic parking brake indicating light switch

Hey John, Pretty much what I ended up doing. Made up pigtail adapters for the screw on terminals and installed the switch. WORKS GREAT! Ordered a spade terminal switch for a spare. I am very appreciative for all the great imputs. Was really stressing over what should be a relatively easy fix. Thanks...

Ok. Thanks for all the input. My concern with it is not knowing the operating pressures. Maybe just overthinking it. Thanks again taking the time.

Re: Hydraulic parking brake indicating light switch

Correction Duane,
I hadn't previously mentioned that it is a hydraulic pressure switch. I compare it to a sending unit on an old car. Not knowing the pressures this switch is operating at, I'm having problems doing a cross reference.
Thanks again,
Jay

Hydraulic parking brake indicating light switch

Hi,
I have a 2002 safari Zanzibar with a hydraulic parking brake. ( Not Autopark) There is a dual terminal normally closed switch for the parking brake indicator light. this switch was originally manufactured by Hobbs Corp. Does anyone know a good p/n for a replacement switch?
Thank You,
Jay
