In looking homes, I've begun to see what they call air or pneumatic switches to control disposals. In almost all instances, these have been mounted vertically in the cabinet tops, toward the side of the faucet. I don't know if code now requires this type of switch or whether it's now just in vogue. I can see some slight safety gain in not having an electrical connection near the sink and can see some added convenience by having it close to the faucet.
My concern is that in the ones I've tried, there is quite a bit of clearance between the button itself and the housing. The resulting void around the button would surely become a mess when a soapy finger would press the button. Have any of you used this type of on/off switch for your disposal and how do you keep it clean and not let it get gunked up? Are they reliable?
