Embodiment

As Fig. 1 and the utility model first specific embodiment shown in Figure 10, a kind of slide switch with lock comprises Lock Part 1, locking spring 7, pushes away handle 2, transfer strip 9, transfer strip spring 8, sleeve 5, sleeve spring 4, shell 3, terminal 10 and base 6.Terminal 10 is inserted in base 6 corresponding installing holes, as shown in Figure 9.Locking spring 7 is contained on two cylinders of Lock Part 1 bottom, and Lock Part 1 is installed in pushes away in the handle 2, and locking spring 7 contacts with pushing away handle 2 relevant positions, as shown in Figure 8.The handle that pushes away that installs Lock Part 1 is placed in shell 3, sleeve spring 4 is contained in the hole that pushes away handle 2 centres, transfer strip spring 8 is put into pushed away handle 2 four circular holes all around, as shown in Figure 6.Sleeve 5 hole heart alignment sleeve springs 4 are packed into pushes away handle 2 centre bores, and the transfer strip 9 two ends salient points two transfer strip springs 8 that align respectively are placed on and push away on the handle 2, as shown in Figure 7.The base 6 that will install terminal 10 at last buckles into shell 3, terminal 10 protuberate basic units.

As Fig. 4 and shown in Figure 5, shell 3 inside top both sides are provided with breach 31, and Lock Part 1 is provided with the card base 11 that can buckle into shell 3 breach 31.

Sleeve 5 one ends contact with base 6 inwalls, installing sleeve spring 4 in the hole of the other end, and sleeve spring 4 contacts with pushing away handle 2 endoporus, pushes away handle 2 and be adjacent to the cover top portion inboard under the effect of sleeve spring 4.
