Appearance & Dimensions : Refer to the drawing 3. Electrical arrangement : single pole, single throw (The two terminlas are either connected together or disconnected from each other) 4. Arrangement of operation : Tactile feed-back 5. Maximum rating : D.C 12V, 50mA
7. Mechanical requirements
â–¶Operating forcePlace the switch such that the direction of switch operation is vertical.And then gradually increasing load is applied to the center of Stem, the maximum load required for the Stem to come to a stop shall be measured.
REQUIREMENTS : 200±70gf
â–¶Travel Place the switch such that the direction of switch operation is vertical. And then apply a static load twice the operating force to the center of the stem, the travel distance for the Stem to come to a stop shall be measured.
REQUIREMENTS : 0.30±0.1mm ▶Return force A switch is installed such that the direction of switch operation is vertical. Upon depression of the Stem in its center the whole travel distance, the force of the Stem to return to its free position shall be measured. REQUIREMENTS : 50 gf Min. ▶Static strength Placing the switch such that the direction of switch operation is vertical. And a static load of 3kgf shall be applied in the direction of Stem operation for a period of 60 seconds. REQUIREMENTS : There is no damage from mechanical and electrical degradation
â–¶Stem strength Placing the switch such that direction of switch operation is vertical. And the maximum force to withstand a pull applied opposite to the direction of Stem operation shall be measured. REQUIREMENTS : 1 kgf Min.(About 3kgf)
