23
/ 14 • • • Tumblers  

23
/ 16 • • • Driving mechanisms  

23
/ 18 • • • • incorporating lost motion  

23
/ 20 • • • • having snap action  

23
/ 22 • • • • with means for introducing a predetermined time delay  

23
/ 24 • with two operating positions  

23
/ 26 • • one of which positions is unstable  

23
/ 28 • with three operating positions  

23
/ 30 • • with stable centre position and one or both end positions unstable  
 

 25
/ 00 Switches with compound movement of handle or other operating part

25
/ 04 • Operating part movable angularly in more than one plane, e.g. joystick  

25
/ 06 • Operating part movable both angularly and rectilinearly, the rectilinear movement being along the axis of angular movement  
 

 27
/ 00 Switches operated by a removable member, e.g. key, plug, plate; Switches operated by setting members according to a single predetermined combination out of several possible settings (locking switch parts to prevent operation H 01 H 9/28; combined with plug-and-socket connectors H 01 R; with current-carrying plug H 01 R 31/08)

27
/ 04 • Insulating plug or plate inserted between normally-closed contacts  

27
/ 06 • Key inserted and then turned to effect operation of the switch  

27
/ 08 • • wherein the key cannot be removed until the switch is returned to its original position  

27
/ 10 • Switch operated by setting members according to a single predetermined combination out of several possible settings  
 

 29
/ 00 Switches having at least one liquid contact (solid contacts wetted or soaked with mercury H 01 H 1/08 )

29
/ 02 • Details  

29
/ 04 • • Contacts; Containers for liquid contacts  

29
/ 06 • • • Liquid contacts characterised by the material thereof  

29
/ 08 • • Means for introducing a predetermined time delay  

29
/ 10 • • • by constricting the flow of the contact liquid  

29
/ 12 • • Operating mechanisms adapted for operation by a part of the human body other than the hand, e.g. by foot  

29
/ 14 • • Operating mechanisms adapted for actuation at a limit or other predetermined position in the path of a body, the relative movement of switch and body being primarily for a purpose other than the actuation of the switch, e.g. door switch, limit switch, floor-levelling switch of a lift  

29
/ 16 • operated by dipping solid contact into stationary contact liquid  

29
/ 18 • with level of surface of contact liquid displaced by non-electrical contact-making plunger  

29
/ 20 • operated by tilting contact-liquid container (centrifugal mercury switches H 01 H 29/26)  

29
/ 22 • • wherein contact is made and broken between liquid and solid  

29
/ 24 • • wherein contact is made and broken between liquid and liquid  

29
/ 26 • with level of surface of contact liquid displaced by centrifugal action  

29
/ 28 • with level of surface of contact liquid displaced by fluid pressure  

29
/ 30 • with level of surface of contact liquid displaced by expansion or evaporation thereof  

29
/ 32 • with contact made by a liquid jet, e.g. earthing switch with contact made by jet of water (operated by direct electrodynamic action H 01 H 53/00)
