I'm trying to build a controller for an operating accessory (the K-Line operating dairy depot). The original controller (now missing but picture pasted at bottom) had a sliding on/off button to power a conveyor belt and a second momentary push button to eject milk cans into a waiting car. I thought I could get a on/off button and momentary push button from RadioShack and wire them up but am clearly doing something wrong. I've posted a picture of how I currently have it wired and in this configuration the on/off switch causes the conveyor belt to work properly but the momentary switch only stops the conveyor belt rather than activating the eject mechanism. Any wiring experts out there no what I'm doing wrong?
