Bought this Protech 42-24196-84 -1.5" WC SPST NO pressure switch for 1/3 the price of Honeywell 42-101956-04.Received it next day in Toronto area with free shipping.The port location is different than Honeywell, but mounting bracket is identical, just a little longer.This switch is smaller than Honeywell, but it perform identical. The manufacturing location is Costa RicaIt comes with a pair of wire with blade connectors, and black vacuum hose. I didn't use those as the sensor fit directly into my existing furnace.The pressure written in Honeywell is 1.5" WC PF, while Protech written as -1.5" WC. I though I got a wrong model, even though I found older Honeywell model 42-24196-04 replaced older 42-101956-04.Turn on the heat by adjusting the thermostat to higher temperature. Immediately I heard the furnace is operating, so the pressure is in fact -1.5" WC PF, not +1.5" WC as written in Honeywell.Pros:1. Cheaper than Honeywell2. Smaller3. Lighter4. Same mounting screw5. Comes with bracket6. Same blade connector sizeCons:1. Hose port is different locationFeel good quality. Giving 5 stars, and strongly recommend to buy
