French CROUZET micro switch operating rules and common classification instructions

French CROUZET micro switch operating rules and common classification
High-nosed CROUZET micro switch use precautions
1) When fixing the main body of the switch, use a small screw of M2 to fix it on a smooth surface with a torque of 0.098 N·m or less. In addition, to prevent loosening of the screws, it is recommended to use washers at the same time.
2) Please note that the action body should not exert force directly on the button or the exciter in the free state. When using it, the button should exert force in the vertical direction.
3) The operation setting after the operation is based on 70% [%] or more of the O.T. value. In the case of a switch, do not set the operating body at the operating limit position to avoid the opening and closing and over-traveling of the impact.
2. Changes in the characteristics of the action
Regarding the change in the operational characteristics, no malfunction should be caused even if the ±20 [%] of the operational characteristic specification value changes.
3. About welding operations
In the case of hand soldering, use an electric temperature with a temperature adjustment of 320 ° Cmax.) to complete the work within 3 seconds, and be careful not to apply force to the terminal portion during the work.
4. When using at low current and voltage, it is recommended to use a low power circuit type (Au cladding contact).
5. Environment
High North CROUZET micro switch classification
Microswitches, as the name suggests, use very small force switches. The electric shock is small and the torque is large. Generally there are drive rods on the outside. Small in size, ultra-small, super small, etc. Functionally, it is waterproof. The most common application is the mouse button.
1. Small micro switch:
The general size is 27.8 wide, 10.3 high and 15.9, and the parameters are high in capacity and low in load. Such as the V3 series:
Operating Frequency (mechanical).....120 operations / mim
Operating Frequency (electrical).....All ratings-10~30 operations / mim
Contact Resistance (initial).....30m Ω (Max.)
Insulation Resistance (at 500VDC).....100M Ω (Min.)
Dielectric Strength (50-60Hz).....1000VAC RMS
Service Life (mechanical).....Min. 5000000 operations
Service Life (electrical).....Min. 10000 operations
2. Ultra-small micro switch
The general size is 19.8 Width 6.4 High and 10.2, which has different performances with high precision and long life. Such as the SM series:
Operating Frequency (mechanical).....120 operations / mim
Operating Frequency (electrical).....10~30 operations / mim
Contact Resistance (initial).....300m Ω (Max.)
Insulation Resistance (at 500VDC).....100M Ω (Min.)
Dielectric Strength (50-60Hz).....1000VAC RMS
Service Life (mechanical).....Min. 10000000 operations
Service Life (electrical).....Min. 6000 operations
3. Super small micro switch
The general size is 12.8 wide and 5.8 high and 6.5. This type has a very thin design. Such as DF series
Operating Frequency (mechanical).....120 operations / mim
Operating Frequency (electrical).....0.1A-120,3A-10~30 operations / mim
Contact Resistance (initial).....100m Ω (Max.)
Insulation Resistance (at 500VDC).....100M Ω (Min.)
Dielectric Strength (50-60Hz).....1000VAC RMS
Service Life (mechanical).....Min. 1000000 operations
Service Life (electrical).....3A-Min. 10000 operations
4. Waterproof
These products have a waterproof rating of IP67, such as the SW series:
Operating Frequency (mechanical).....120 operations / mim
Operating Frequency (electrical).....10~30 operations / mim
Contact Resistance (initial).....30m Ω (Max.)
Insulation Resistance (at 500VDC).....100M Ω (Min.)
Dielectric Strength (50-60Hz).....1000VAC RMS
Service Life (mechanical).....Min. 2000000 operations
Service Life (electrical).....Min. 10000 operations
