So with a newly quired Bally Special Force I noticed that it had some issues with registering balls that drained, sometimes spitting out two balls in plunger lane etc. On closer inspection, I discovered that
1) This machine (and others like it guess) has some strange metal actuator switches which Ive nver seen before.
2) The first and third metal switch was reeeeal sticky, see video here:
I got curious as to why Bally started (and then stopped apparently) using these type of metal switches, and also if anyone know the exact part number for them (if I need to replace them), and if there is any trick to deassembling these or if its just to remove the screws holding the whole trough assembly and then lift it out?
