D2FS Ultra Subminiature Basic Switch
Simple Construction and High Reliability for Long Time
- Developed for a few number of operations during a long period of use such as door-detection to avoid sabotage on meters.
- Simple construction with a single-leaf movable spring realizes reasonable cost.
- Self-clinching, right-angled and left-angled PCB terminals are also available.

|The following illustrations and drawings are for D2FS models with PCB terminals (straight). Self-clinching, and right-angled, left angled terminals are omitted from the following drawings. Refer to the above for these terminals. When ordering, replace with the code for the terminal that you need. See the "List of Models" for available combinations of models.|

Note: 1. Unless otherwise specified, a tolerance of 0.4 mm applies to all dimensions.
2. The operating characteristics are for operation in the A direction ().
When using automatic soldering baths, we recommend soldering at 260°C within 5 seconds. Make sure that the liquid surface of the solder does not flow over the edge of the board.
When soldering terminals manually, perform soldering within 3 seconds at iron tip temperature not higher than 350°C. Do not apply any external force for at least 1 minute after soldering. When applying solder, keep the solder away from the case of the Switch and do not allow solder or flux to flow into the case.
●Side-actuated (Cam/Dog) Operation
When using a cam or dog to operate the Switch, factors such as the operating speed, operating frequency, push-button indentation, and material and shape of the cam or dog will
affect the durability of the Switch. Confirm performance specifications under actual operating conditions before using the Switch in applications.
When handling the Switch, ensure that uneven pressure or, as shown in the following diagram, pressure in a direction other than the operating direction is not applied to the Actuator, otherwise the Actuator or Switch may be damaged, or durability may be decreased.
●Using Micro Loads
Even when using micro load models within the operating range, inrush currents or surges may decrease the life expectancy of the Switch. Therefore, insert a contact protection circuit where necessary.
Do not use the Switch in locations that are subject to toxic gas, silicon, excessive dust, excessive dirt, high temperatures, high humidity, sudden temperature changes, water splashes, or oil splashes.
Otherwise, damage resulting by faulty contact of the Switch contacts, corrosion, or other causes, or other functional faults may occur.
