I bought this switch, it has 5 terminals: H M L B C. The fan motor had 4 wires Black, Blue, Red, Yellow. I didn’t have much to go on, as the old switch was pretty trashed out. Black fan wire was put on L, Blue fan wire on M, and Red fan wire on H. The electric cord was a two pronged extension cord which I cut the outlet end off. The cord has a black (hot) wire and a white (neutral) wire. Attach the hot wire to B terminal and connect the white neutral wire to the remaining yellow wire of the fan. Do not connect them to C. I made the mistake of attaching the white and yellow to C and I had to replace the wall outlet! It took less than a fraction of a second to get really hot and blow. Luckily, no damage was done to the switch or fan and the outlet was replaced! I’m happy to report that somebody on desertcart who also had left a review for this switch said C terminal wasn’t used in this case. Also happy that all is working good on this old fan. First click is High speed, second click is Medium speed, then the third click is Low speed. Then when you turn the switch counterclockwise, it goes to M then H then off. ## Features - Product name:4 Position Rotary Switch(4 Position 3 Speed);Action Type:latching. - Product size:Overall dimensions:50.5mm/30mm/30mm(2in/1.2in/1.2in);Thread diameter:9.7mm/0.38in.Materials: Plastic,metal. - Product parameters:Mechanical life:10,000 cycles;Rated Voltage & Current:16A 120VAC/12A 250VAC;5 terminals. - Easy to use:4 positions(0-1-2-3):Position 1:(B - C)/(B - L)/(B - M)/(B - H)OFF;Position 2:(B - C - L)ON,(B - M)/(B - H) OFF;Position 3:(B -C - M)ON,(B - L)/(B - H)OFF;Position 4: (B - C - H)ON,(B - L )/(B - M)OFF. - Product packaging:1 x Rotary Switch+1 x Knob+1 x nut + 5 x terminals. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09P9T86TT | | Actuator Type | Rotary | | Best Sellers Rank | #33,974 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #11 in Selector Switches | | Brand | Taiss | | Brand Name | Taiss | | Circuit Type | 4-way | | Connectivity Protocol | X-10 | | Connector Type | Plug In | | Contact Material | Metal | | Contact Type | Normally Closed | | Control Method | Touch | | Current Rating | 12 Amps, 16 Amps | | Customer Reviews | 4.4 out of 5 stars 283 Reviews | | International Protection Rating | IP65 | | Item Dimensions | 1.18 x 1.18 x 1.97 inches | | Manufacturer | Taiss | | Material Type | Metal, Plastic | | Model | F-040 | | Mounting Type | Surface Mount | | Number of Items | 1 | | Number of Positions | 4 | | Operating Voltage | 125 Volts | | Operation Mode | ON-OFF | | Switch Type | Rotary | | Terminal | Through Hole | | Unit Count | 1.0 Count | | Wattage | 3000 watts | ## Product Details - **Brand:** Taiss - **Connector Type:** Plug In - **Contact Type:** Normally Closed - **Current Rating:** 12 Amps, 16 Amps - **Item dimensions L x W x H:** 1.18 x 1.18 x 1.97 inches - **Material:** Metal, Plastic - **Operating Voltage:** 125 Volts - **Operation Mode:** ON-OFF - **Switch Type:** Rotary - **Terminal:** Through Hole ## Images ![Taiss Rotary Switch 4 Position 3 Speed Fan Switch 12A 250V/16A 125V Metal Fan Heater Speed Selector Switch with Knob and terminals F-040 - Image 1](https://m.media-amazon.com/images/I/61bHL8+bSEL.jpg) ## Questions & Answers **Q: Does this come with wiring instructions for blower fans?** A: Not really inst.for blower has inst. For wiring. **Q: I need a 4-position switch for a DC project. Does this alter the current for the positions, or does it just send the current to the terminals?** A: Just sends the voltage to the terminal that is switched to. Current is dependent upon the load at the different terminals. **Q: My current golf cart fan switch only has two wires for the previous 3 speed fan. Can this be wired for 3 speeds or will only one speed be its option?** A: I believe the switch you have is a rheostat switch, it can send different voltage to the fan to control the fan speed. This switch sends the same voltage to 3 different wires in the fan motor with a different winding which then controls the fan speed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by M***J on January 7, 2026* This thing is heavy duty and work perfectly to replace my three-speed fan switch in my outdoor range hood ### ⭐⭐⭐⭐⭐ Terminal C on switch was not used *by D***S on June 26, 2024* I had a vintage hassock fan that needed a new switch and electric cord.
