IEC61058-1 clause 17.2.3 and 17.2.4
17.2.3 Manual and mechanical conditions
17.2.3.1 The switches are operated by means of its actuating member either manually or by an appropriate apparatus which is arranged to simulate normal actuation.
The operating speed for the operating cycles shall be as follows:
For the tests of switches except electronic switches:
a) for slow speed:
– approximately 9°/s for rotary actuations at an angle of operation 45°;
– approximately 18°/s for rotary actuations at an angle of operation >45°;
– approximately 20 mm/s for linear actuations.
b) for high speed, the actuating member shall be actuated by hand as fast as possible. If a switch is normally provided without an actuating member, then a suitable actuating member should be supplied by the manufacturer for the purpose of this test.
c) for accelerated speed:
– approximately 45°/s for rotary actuations at an angle of operation ≤45°;
– approximately 90°/s for rotary actuations at an angle of operation >45°;
– approximately 80 mm/s for linear actuation
For the tests of electronic switches:
d) for slow speed:
– approximately 9°/s for rotary actions;
– approximately 5 mm/s for linear actions;
e) for high speed, the actuation member shall be actuated by hand as fast as possible. If a switch is delivered without an actuating member, then a suitable actuating member should be supplied by the manufacturer for the purpose of this test;
f) for accelerated speed:
– approximately 45°/s for rotary actions,
– approximately 25 mm/s for linear actions
17.2.4.10 Test at very slow speed (TC10)
The electrical conditions are those specified in 17.2.1.
The switches are operated by means of its actuating member by an appropriate apparatus which is arranged to simulate normal actuation.
The operating speed for the operating cycles shall be for mechanical switches as follows:
– approximately 1°/s for rotary actuation;
– approximately 0,5 mm/s for linear actuation.
The number of operating cycles is 100.
Instrument
Switch should withstand the mechanical stresses occur duringnormal use of electricity and thermal stresses without excessive wear or otherharmful effects appear.
